Foxflash Failed to Write Opel Delco E98 via OBD?

Problem:

Foxflash read Opel Astra Delco E98 ok, but failed to write via OBD, error DAT1. Any solution?

Solution:

Raise voltage.

If still fails, do it via Full system. Don’t connect bench box if doing full system.

Tested by many without problem on bench.
